System and method of selecting GGSN in a mobile communications network

摘要

A method and system of determining a GGSN to serve data calls in a mobile communications network is provided. Messages are received from a SGSN, and analyzed to determine if the message is requesting the identity of a GGSN. If the received message is requesting the identity of a GGSN, a GGSN selection algorithm is executed to identify a GGSN to serve data calls from a specified MS. A reply is then constructed and sent to the SGSN identifying the selected GGSN.
